Updated as of 12:02 p.m. on Jan. 31 | The Capitol is a busy place most Tuesdays, but this Tuesday was special. President Donald Trump’s first State of the Union address at 9 p.m. ET made for a chaotic (and long) day for lawmakers, their aides, reporters and Capitol staff.

The Supreme Court will decide whether businesses must collect sales tax on online transactions in states where they don’t have a physical presence, in a case closely watched by lawmakers, states and online retailers.

The case gives the justices a chance to reshape internet commerce, something Congress hasn’t done since the high court last ruled on the issue in 1992. Back then, the court barred states from collecting sales tax from vendors that were out of state.

Federal Communications Commission Chairman Ajit Pai vowed to pull government “out of the newsroom” by changing media ownership rules. As he appeared before a House panel Wednesday, Pai proposed to end longstanding restrictions on ownership of daily newspapers and broadcast radio or television stations serving the same community.

Pai also deflected criticism from Democrats that he did not offer a more forceful defense of NBC and other networks against social media jabs by President Donald Trump. The president raised the prospect of revoking NBC’s license after one of its news reports early this month.

While much speculation over House leadership changes in the 115th Congress is focused on a contentious speaker’s election that may never materialize, a long series of intraparty leadership, committee and caucus races guarantee significant turnover in top House posts next year.

Retirements, term limits and lawmakers departing for other jobs mean that at least 17 prominent roles, and likely more, will change hands. Elections to determine those new influencers are set to begin during the lame-duck session that opens the week after Election Day.
